Overly complicated never looked so simple

Tonight I finally got the rear brake on the BSA put together. What your looking at is a mechanical sprotor. I designed the rear caliper around a simple mechanical brake you find on industrial machines. The way it will work is the left rear set control will actuate it via a wedge which pushes up between the two adjustable ball bearings, pushing the arms open and the brake pads together. The brake arms are aluminum and most everything else is stainless. I still need to rivet the brake shoe material to the backing plates.


  1. chris that is amazing...i cant wait to see this thing finished....

  2. nice mechanicals. Do you have a photo of how the foot pedal wedges the levers open?
